Illuminations are extended examples designed to help teachers think about how they might apply the ideas of NCTM's Principles and Standards for School Mathematics in their daily practice. Contents include:

Shockwave activities illustrating real-time correlations between equations and graphs, designed to help students visualize and experiment with concepts from elementary algebra through pre-calculus. Graphs of functions, systems, and complex numbers are included.

In addition to slide-bars for varying parameters and values of variables, most activities allow zooming and panning in the plane, data exportation, screen snapshots, and tooltip help. The site also allows members to create and view Web pages for mathematics courses.
